OPTICAL POSITION MEASURING DEVICE

摘要

The invention relates to an optical position measuring device which is used to determine the relative position of a sampling unit and a material measure which can be displaced at least in one measuring direction and which is arranged on the material measure plane. Said material measure extends along a first straight line or a curved line. Said sampling unit comprises a light source and a detector arrangement which extends along a second line and which is arranged on a detection plane, said curve being different from the first straight line or the first curved line. A stripe pattern resulting in the sampling of the material measure transforms into a stripe pattern extending along the second line. The material measure plane and the detection plane are not parallel to each other for transformation.
